LEATHER-FINISHING- MACHINE.

Application filed October 29, 1913.

To all whom it may concern:

V Be it known that I, FRANK F. SLoooMn, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania. have invented a new and useful Leather-Finishing Machine, of which the following is a specification.

My present invention consists of a novel leather finishing machine wherein novel means are provided for preventing'the turning over of the leather by the brush rolls as it passes between such brush rolls and the surface of the drum.

It further consists of means for adjusting the position of such means with relation to the brush rolls and the leather to be treated.

It further consists of a novel leather finishing machine wherein is employed a plurality of brush rolls and in conjunction therewith holding devices are provided eX- tending into the brushes of said rolls and arranged at varying positions on the different rolls, so that the impression left on the skin by the holding devices of one roll will not be coincident with the impression left on the skin by the holding devices of another roll.

In a prior patent granted to .me and \Villiam E. Poinsett, on August 10th, 1909, No. 930,700, we have shown and broadly claimed novel means for preventing the turning over of the leather by the brush rolls, and my present invention while commg withm the broad and generic scope of the patent above referred to, 1s directed to a somewhat different construction from that shown in said patent.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have'shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is -not limited to the precise Specification of Letters Patent.

arrangement and organization of these instrumentalities as herein shown and, described. 5

Figure 1 represents a sectional elevation of a leather finishing machine embodying my invention. Fig. 2 represents a top plan view thereof. Fig. 3 represents a plan view of the leather retaining means in detached position. Fig. 4 represents a sectional View of the leather holding device. Fig. 5 represents a sectional view of a portion of the machine showing more clearly the manner of adjusting the container for the finishing material. Fig. 6 represents a side elevation. of a portion of the machine showing more clearly certain details of construction.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the frame of the machine in which is mounted a driving shaft 2 provided with pulleys 3 and at thereon, one of which is loose and the other fixed with respect to said driving shaft. The driving shaft 2 has fixed thereon a pinion 5 which meshes with a gear 6 mounted on a shaft 7 suitably j ournaled in the machine frame. The shaft 7 has fixedly secured thereto apinion S which meshes with a gear 9 mounted on a shaft 10 j ournaled in the frame 1. The shaft 10 has fixedly mounted thereon a drum which serves as a support for the leather or skin which is to be-treated. The shaft 2 is provided with a pulley 11 around which passes a belt 12 which latter also passes around a pulley 13, which latter is mounted on a shaft 14 journaled in the machine frame. The shaft lat carries a brush 15 which is adapted to revolve within a container 16 for the finishing material. The position of the container 16 with respect to the brush 15 may be'varied by means of the adjusting screws 17 which are in threaded engagement with the container, as seen at 56, Fig. 5, it being under stood that the longitudinal movement of the adjusting screws 17 is prevented by means of the set collar 57.

18 designates a transfer roll or brush mounted in journal bearings 19, the boxes of which are guided in the slots 20 and provided with adjusting screws 21.

22 designates a brush roll mounted in journal bearings 23 the boxes of which are guided in slots 24: and provided with adjusting screws 25.

26 designates a brush roll mounted in journal bearings 27 the boxes of which are guided in slots 28 and provided with adjusting screws 29.

30 designates a brush roll mounted in journal bearings 31, the boxes of which are guided in the slots 32 and provided with ad justing screws 38.,

The shaft 1-1 of the brush 15 has fixed thereon a gear 34 which meshes with a gear 35 on the shaft of the transfer roll 18. The gear meshes with a gear 36 on the shaft of the brush roll 22. The shaft 1 1 is also provided with a pulley 38, see Fig. 2, around which passes a belt 39 which latter also passes around a pulley 10 on the shaft of-the brush roll 26. 11 designates a belt which also passes aroundthe pulley 10 and around a pulley 42 on the shaft of the brush roll 30.

It will be understood that by means of the connections hereinbefore described. the different rolls and the drum are revolved in the directions indicated by the arrows in Fig. 1.

Referring now to the novel means employed for preventing the turning over of the leather during the finishing operation, it will be seen that the same comprises a bar or frame 13 to which are secured. the members 4A: in a manner best illustrated in Fig. 1. The members or bars 14-. have their inner ends deflected upwardly and laterally so as to pass through apertures in the bar =13 and be fixed in assembled. position with respect thereto by means of the fastening devices 15, illustrated as consisting of screws. The members 44: consist of bars or rods shaped to conform to the operative surface of the leather support and since such support has been illustrated as consisting of a drum, said members ea are slightly curved and the outer ends are preferably upwardly or outwardly deflected. The ends of the bar 13 are connected with supporting arms i6 which are secured thereto by means of fastening devices 47 consisting, in the pres ent instance, of washers and of nuts in threaded engagement with the ends of the bars or threaded rods connected therewith. The free ends of the supporting arms 46 are rearwardly deflected to form slots 48, see Fig. 1,whereby the leather holding devices may be adjusted in a radial or other direction with respect to the drum 55 or the brush roll.

I preferably employ a leather holding device to-operate in conjunction with each brush roll, such as 22, 26 and 80, and secure such devices in position by means of bolts a9 carried by the frame 1 and passing through the slots 928, said bolts beingprovided with'nuts 50 whereby the leather hold-.. mg devices are maintained in their adjusted position.

"51 designates a table carried by a bracket 52 and terminating in proximity to the drum 55.

A drip-tank 53 is preferably provided and supported in any desired manner, said tank being provided with a discharge conduit 54: leading to a desired point of utilization.

In the operation, the driving shaft" ,2: is driven by any desired source of motive power whereupon, as is evident, the drum 55 and the different rolls will be actuated in the directions of the arrows seen in Fig. 1.

The leather or skin 58 to be treated is fed fromthe table 51 on to the leather support 55 which, in the present instance, is the re volving drum, and passes beneath the brush rolls 22, 26 and 30 so that the leather finishing material which'is fed to the skins from the container 16 by means ofthe brush15,

transfer roll 18 and brush roll 22 is worked into the leather or skin in a very efficient vergence of the bristles on the next roll. In.

the present instance, I have preferred to show these members 4% as located a slight distance above the leather beingtreatcd so that they are normally out of contact there with but such devices are adjusted in such a. manner that they positively prevent any turning over of the leather during the brushing operation.

The container 16 for the leather finishing material may bereadily adjusted with" respect to the brush 15 by actuating the set screws 17... The transfer roll may be adjusted withrespect to the parts cooperating therewith by adjusting the set screws 21. The brush rolls 22, 26 and 30 may be readily adjusted with respect to the leather. supporting drum 55 by actuating the set screws 25, 29 and 33 respectively, as will be apparent to those skilled in-this art.-

For the. purpose of illustrating one manner of carrying out my invention inpractice, I have shown the members 1 1 of a leather holding deviceas arranged substantially parallel with each other.

It will be apparent from the construction seen in Fig. 6, which is an end view. of the upper portion of one side of the machine,

that I have provided a convenient and readily manipulated adjusting means whereby the brushes can be readily moved toward or away from the material to be treated, it being of course understood that the construction seen in Fig. 6 is employed upon both ends of the bearings for the brush rolls. I have deemed it unnecessary to show a detailed view of each end of the machine,

, since it is thought that the construction and arrangement of the power transmission devices shown in Figs. 1 and 2 will be clearly apparent to those skilled in the art and it will furthermore be apparent that I may employ other means than that shown for the purpose of rotating the drum 55 and the various other operative parts of the machine, such as the brush rolls 15, 18, 22, 26 and 30. It will furthermore be apparent that I can employ other means for supporting and adjusting the fingers or members 4 1 and that the same may be attached to their supports as the bar as by other devices than that shown. It will furthermore be apparent that while my invention is particularly designed for the treatment of skins or leather,'it may be employed with equal facility in the treatment, coating or finishing of other articles than skins or leather, as will be apparent to those skilled in the art.

I desire to call special attention to the advantages attained for the employment of the laterally extending members or fingers 44 which are arranged in such relation to each other and to the brush rolls that there will be no streaks or marks left upon the article which is being treated or finished after its delivery from the machine. As a result of the arrangement and collocation of the guide members or fingers 44 in staggered order, every portion of the article to be treated will be retained in the desired position with respect to the drum and the rolls during the finishing operation, as is evident.

It will now be apparent that I have devised a novel and useful construction of a leather finishing machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars Without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is
